KEY MESSAGES

Issued at 1141 PM CDT Sun Sep 27 2026

- A moderate excessive rainfall outlook remains in place along the central to western combined Panhandles. Meaning there is at least a 55% chance of seeing rainfall exceeding flash flood guidance within 25 miles of a point.

- There will be potential for high winds behind a cold front Thursday. The cold front is expected to bring below normal afternoon temps for Friday.

SHORT TERM

(Tonight through Tuesday night) Issued at 1141 PM CDT Sun Sep 27 2026

One more day of highs in the mid to upper 80s is expected today as an upper level ridge maintains some influence before shifting east. As this ridge shift east, southwest flow increases and so does Pacific moisture. Going into the evening PoPs begin to pick up first in the far NW to W combined Panhandles. Before sunrise those PoPs pick up to 20 to 50 in the western half of the Panhandles. Just after sunrise, likely to see PoPs increase to 70 to 90 in the west.

Tuesday morning after Hurricane Polo smacks into the Baja Peninsula, the system begins to fall apart over western Mexico, it will begin to get ingested into the main flow of an approaching upper level trough. The low associated with this trough is expected to be over the southern most tip of NV as it begins to strengthen moving into AZ through the day on Tue. Even though Polo is expected to fall apart is expected to transport quite a bit of atmospheric moisture into the southwest flow aloft. Still expecting a potential for heavy rain and flood potential due to this abundant moisture and stout system coming into the Desert Southwest.

LONG TERM

(Wednesday through next Sunday) Issued at 1141 PM CDT Sun Sep 27 2026

Wednesday's rain chances will be highly contingent on how the aforementioned upper level low comes across. The low may potentially come across the Southern Great Plains in such a way that the central to southwestern parts of the Panhandles end up getting dry slotted with the eastern and northern portions getting some additional rounds of rain. The eastern parts of the Panhandles getting more rain on Wed/Wed night may only be the case if the low doesn't move off too fast and dry slots that area. There will also be chances for wrap around moisture to add additional rounds of light to moderate showers Thu and Thu night. For now extra cloud cover is expected to keep afternoon temperatures cooler in the 70s for the most part through the weekend. With Friday potentially having the coolest temps, potentially staying in the upper 60s. This will be thanks to the arrival of a cold front Thursday. This cold front on Thursday may also bring in some strong northerly winds behind it, and would not rule out potential headlines like a wind advisory.
